I am working on a project for which I need to show a certain url in the address bar for e.g. www.abc.com/contact.htmlwhen there is no such page contact.html in the project , instead there is a page frame_contact.php.....I need to display the url ..../contact.html in the window address bar and redirect the page to frame_contact.php

I am sorry If that is a very basic question , because I am new to the language.
